How to reset my locked iPhone 4s?

So my ex changed the passcode on my phone, and I have no clue what it is, and have been trying for days now to figure it out… Is there anything I can do without going to the Apple store? I don't have one near me, so I'm trying to see how I can just reset the phone, but I haven't found a solution as of yet.

The suggestion to hold the home & lock button for five seconds does not work, because this is the 4s, that just brings up Siri, and doesn't do anything to the phone.

Any suggestions?

How to move iPhone music and other things to iCloud or something like it?

Why is our generation so messed up?

I'm a 13 year old girl and i just don't understand why:
1.) people kiss their girlfriend/boyfriend in front of everyone in school. I mean in school you can talk, but I don't want to see you trading tongues.
2.) girls where three inches of makeup and think they are pretty when they look like clowns.
3.) boys wear their pants low and look retarded. I don't want to see your underwear and that originated somewhere i don't want to talk about.
4.) the music sucks. I have nothing against these music artists, but some are fake and can't sing.
5.) kids think its cool to not do work and get F's and do drugs and bully.
6.) if kids don't get what they want they get emo and suicidal. Who cries because you don't have an iPhone or that "adorable" shirt.
I understand that there are kids that aren't like this. I love those type of people.

Added (1). It's hard to stop giving a damn about them if they won't stop giving a damn about me.

Added (2). Is there an age requirement to be asking this question? As i said before i can't ignore and live my own life because these people and stuff are getting into my daily life. I'm doing the best i can to ignore them, but they don't ignore me.
